After the first week of having my first chicks, I decided to change to sand in the brooder; it's now been another full week since I changed. It ain't perfect, but at least the sand dust doesn't bother my throat and lungs the way the pine shavings were, and I believe my chicks are cleaner.
Needless to say, they have as much sand as they want and there have been no repercussions. Yes, they pecked at it like crazy, at first, but that quickly wore off. Once the sand heats under the heat lamp, they seemed to really enjoy snuggling down in it.
And I witnessed my first dust bath the other day! Good thing BYC-ers had prepared me for this, because, yes, it looks like she's having a life-ending seizure.
So, I guess what I'm saying is that my experience tells me that sand, even a LOT of it, is not going to hurt them. And no need for extra grit.
